What license level do you have? An Advanced license gives you the most flexibility. However, it is virtually certain that a custom script will be involved that employs cursors and dictionaries to do the analysis to find the closest vertex to the intersection and write a buffer distance field to the intersection point.
Do the lines that make up the line network connecting to the intersection points always have an end that is identical to the intersection point, or do the lines go through the intersection points?
I have ArcGIS advanced license. I agree with you on that a custom script would be needed.
Regarding your question about the lines, I have a polygon layer and there are 52488 polygons.
What I'm trying to do is exactly to find the closest vertex to the intersection and write a buffer
distance field to the intersection point.
I tried to run point distance analysis tool without specifying search radius value but this analysis
takes too much time considering total number of vertices and intersection points. So, It would
If you have a threshold distance to an intersection point, which if memory serves you do,
You should not have a list of intersection points, the intersections with the buffer and their angles.
Those that are in the "todo" list... well figure out what you are going to do. Make an assessment, or process them separately.
Seems to me a good approach would be
